摘　　要：针对硐室围岩岩性差、原有支护设计不合理、无控制底板措施、高地应力作用下硐室围岩发生局部变形破坏。采取在原有一次锚网支护的基础上,采取二次锚网支护加固技术,并针对支护承载结构的薄弱部位,采用锚索对锚网支护形成的承载结构进行结构补偿的支护方式,有效的控制了硐室围岩变形,锚杆失效和载荷分布不均造成的支架承载能力降低。For the question of bad enclosing lithologies of the surrounding rock,the unreasonable of the original support,no baseplate controlmeasure and local deformation of the surrounding rock because of high ground pressure.This thesis put forward a method that adopt secondanchor net supporting on the foundation of the original support, and using anchor cable to make up for the bearing structure formed by anchornet supporting,which effectively control the deformation of the surrounding rock and low carrying capacity of support because of anchor supportfailure and load distribution.

关 键 词：硐室 围岩控制 变形破坏 二次支护
